Insulation 'Expert Heat Aquastop'
Dimension
- thickness 1,5 mm
- width 1 m
- length 10 m
Installation
Before laying, ensure that the floor is suitably prepared, i.e. clean, dry, free of cracks and resistant to tension and pressure. It is not necessary to use an additional vapour barrier as the foil is laminated to the top. The underlay is laid out on the floor (aluminium-laminated foil side facing upwards). Butt the individual sheets together, remove the protective film from the self-adhesive strip and stick the overlapping edge to the self-adhesive strip. It is essential to ensure that the sheets do not overlap at the seams on the long and short sides.
Details
Thanks to its very low thermal resistance value, Expert Heat Aquastop is the ideal underlay for the use of laminate with underfloor heating. Thanks to its sound-absorbing properties, it improves acoustic comfort and consequently provides a high level of walking sound insulation. The self-adhesive edge and the cut lines make Expert Heat Aquastop particularly easy to lay. The 3-in-1 combination underlay is the perfect choice for rooms with medium foot traffic thanks to its good compressive strength.
Why a vapour barrier?
A vapour barrier or vapour retarder is used in the building industry to prevent water vapour from precipitating as condensation in the thermal insulation or flooring. In the laminate flooring sector, the vapour barrier is a film that is usually made of polyethylene (PE film). It prevents moisture from penetrating through the subfloor into the laminate flooring.
We have chosen an insulating underlay that is already equipped with an aluminium foil as a vapour barrier. Is the underlay laid with the silver layer facing upwards or downwards?
The underlay is laid with the coated side facing upwards. Lay the underlay with the aluminium coating slightly overlapping and glue the joints with aluminium adhesive tape. Some of the aluminium underlays already have an integrated adhesive surface.
How do I reduce the walking noise of laminate flooring?
Laminate flooring is made up of individual panels. This can cause noise when you walk on it. The subfloor under the laminate floor also plays a role. To reduce the walking noise on the floor covering, there is no alternative to impact sound insulation. But you have two options here:
- Impact sound insulation as an underlay: Reduce footfall sound by laying an underlay under the laminate flooring. This minimises noise in the room – your neighbours will be grateful too. You will find various types of impact sound insulation in the LOGOCLIC® range.
- Integrated impact sound insulation: The Ambienta product line, for example, impresses with its integrated impact sound insulation. This means that no additional work step is required for impact sound installation when laying laminate. The laminate ideally dampens walking noises thanks to this integrated insulation.
Which is the best insulating underlay to use with underfloor heating?
If laminate flooring is to be laid over underfloor heating, the heat dissipation must be taken into account. If the floor covering insulates too much, the heat of the underfloor heating will be insufficiently used – thus a lot of energy will be lost.
The following reference values should be observed if insulating underlay is to be used with underfloor heating: the total thermal resistance should not exceed 0.15 m2K/W.
When do I need a vapour barrier film?
A vapour barrier is a PE film which protects the laminate from moisture. Because this film prevents moisture rising into the laminate flooring. If moisture were to penetrate the laminate floor, it would lead to swelling and rippling in the floor covering. You will find various types of vapour barrier films in the LOGOCLIC® range.

Which floors are particularly silent?
The laminate Silentos has an integrated impact sound insulation. For the laminate flooring Family you need to lay an insulation carpet pad. This is also done quite easily thanks to integrated adhesive strips.
